I didn't write this but I'm willing to bet there is a good deal of new programmers interested in at least learning about 3D programming even if their language of choice doesn't have a 3D graphics API and the example code used is not in any particular language so:
Check it out if you are interested.

Pertty solid dude...
If only I had read this before I started work on my 3d engine, it would have saved a load of painstaking trial and error bull.

If anybody is seriosuly considering writing an engine, this would be the place to start Very Happy .

You are essentially looking for a projection which projects all the points onto a plane and then connecting/filling them accordingly. This is a rather simpler process using only similar triangles. However, it can get quite messy once you have 40+ points. To make it run faster, you probably need hash charts/quick sorting.
